How do you simplify the square root of 12 divided by 2? Algebra Radicals and Geometry Connections Multiplication and Division of Radicals 1 Answer Konstantinos Michailidis Sep 22, 2015 It is √12 2 = √4 ⋅ 3 2 = 2 ⋅ √3 2 = √3 Answer link. 6\sqrt {2}=\mathbf {12\sqrt {2}} 2. The 2nd root of 25, or 25 radical 2, or the square root of 25 is written as 25 2 = 25 = ± 5. #1 +124713 +2 Note that 2 = √2 * √2 So √2 / 2 = √2 / [√2 * √2 ] = 1 / √2 CPhill Oct 22, 2017 #2 +653 +2 I agree with you CPhill, but isn't a fraction not allowed to have a square root in the denominator? I think we are supposed to multiply both the numerator and denominator by the square root of 2. To divide square roots using radicands, set up the expression as a fraction using one radical sign. 2√3 2 3 The result can be shown in multiple forms. 2 = 2. Inputs for the radicand x can be positive or negative real numbers. Each positive real number always has two square roots – the first is positive, and the second is negative. To divide square roots using radicands, set up the expression as a fraction using one radical sign. Combine square roots under 1 radicand. 12/sqrt (2) = sqrt (144)/sqrt (2) = sqrt (72) = sqrt (9)*sqrt (4)*sqrt (2) = 3*2*sqrt (2) = 6*sqrt (2) Basically you first take 12 and put that it terms of a square root: 12 squared equals 144 so 12 = sqrt (144). Tap for more steps 6√2 6 2. The thing about a square root of a fraction is that: sqrt (35/9) = sqrt (35)/sqrt (9) in other words, the square root of the entire fraction is the same as the square root of the numerator divided by the square. Tap for more steps 12√2 2 12 2 2 Cancel the common factor of 12 12 and 2 2. Since 150 is divisible by 2, we can do this. In mathematics, a quadratic equation is a polynomial equation of the second degree. Free Square Roots calculator - Find square roots of any number step-by-step. Paste it where you want the symbol.
